Historical information

Manually operated sprayers like this were essential tools before modern electric or battery-powered sprayers became widespread.
They provided an affordable and effective method for small-scale farming and domestic gardening.
The durability of brass and copper components made these sprayers long-lasting and repairable, contrasting with modern plastic alternatives.
Used primarily as a garden or agricultural sprayer, often for applying:
Pesticides
Fungicides
Liquid fertilizers
Cleaning agents
The user pumps the handle to pressurize the liquid in the reservoir, then releases it through the nozzle as a fine mist or jet spray.
Such sprayers were commonly used in gardens, orchards, and farms during the early to mid-20th century.
